It seems like the CJ Daily Fix has won, but I'll make a late shout for the Darcy Botanicals Cleansing Cream! I really like it and certainly don't need a rinse out conditioner with it. I haven't tested its cleansing power though as I shapoo once a week still, so it never has to deal with a lot of build up.
I would have to agree that CJ Daily Fix Conditioner is a must have for cowashing that actually gets the hair clean. Nothing worse then stepping out of the shower and you have product buildup lurking in your hair
